	Position the HP Fast InfraRed Receiver within the range of operation

	sure that no object is blocking the connection. (This object could be
	a hand, paper, books, or even bright light.)
	Make sure that the two IR ports are clean (free from dirt and grease).
	Bright light of any kind (sunlight, incandescent light, fluorescent
	light, or light from an infrared remote control, such as those used
	for TVs and VCRs) shining directly into one of the IR ports might
	cause interference. Make sure that no bright light is shining directly
	into either IR port.

	temporary connection interruptions. You have up to 40 seconds to
	re-establish the connection (depending on the portable device
	being used).

The print job has been properly sent, but the printer will not print.

If the connection is broken before the entire print job has been transmitted to the printer (printing has not yet started), the printer may not print any of the job. Press [Cancel Job] to clear the printer’s memory. Then, reposition the portable device within the range of operation described in the user guide for the HP Fast InfraRed Receiver, and print the job again.
